ComfyUI Node: Adjust Neck v4.7.3

Adjust Neck v4.7.3:

The tri3d-adjust-neck node is designed to adjust the neck position in a pose estimation context, ensuring that the neck's alignment and scaling are consistent with a reference pose. This node is particularly useful in applications where precise body part alignment is crucial, such as in animation, virtual try-ons, or augmented reality. By manipulating keypoints, it adjusts the neck's position relative to other facial features like the nose and eyes, maintaining proportionality and alignment with the reference pose. This ensures that the generated pose maintains a natural and realistic appearance, enhancing the overall quality of the output.

Adjust Neck v4.7.3 Input Parameters:

pose_json_file

This parameter specifies the path to the JSON file containing the pose data. The file should include keypoints that represent various body parts, such as the nose, eyes, and shoulders. The node uses this data to adjust the neck's position and scale it relative to the reference pose. The accuracy and quality of the input data directly impact the node's performance, so ensure the JSON file is correctly formatted and contains accurate keypoints.

Adjust Neck v4.7.3 Output Parameters:

adjusted_keypoints

The output of this node is a set of adjusted keypoints, where the neck position has been modified to align with the reference pose. These keypoints can be used in further processing steps, such as rendering or animation, to ensure that the pose appears natural and consistent. The adjusted keypoints maintain the original structure but with improved alignment and scaling, providing a more realistic representation of the pose.

Adjust Neck v4.7.3 Usage Tips:

• Ensure that the input JSON file is correctly formatted and contains accurate keypoints for optimal results.
• Use high-quality reference poses to guide the neck adjustment process, as this will enhance the realism of the output.
• Consider using this node in conjunction with other pose adjustment nodes to achieve comprehensive pose alignment and scaling.

Adjust Neck v4.7.3 Common Errors and Solutions:

"Invalid JSON format"

• Explanation: This error occurs when the input JSON file is not properly formatted or contains syntax errors.
• Solution: Verify the JSON file for any syntax errors and ensure it follows the correct structure for pose data.

"Missing keypoints in input data"

• Explanation: The node requires specific keypoints to perform adjustments, and this error indicates that some keypoints are missing.
• Solution: Check the input JSON file to ensure all necessary keypoints are included and correctly labeled.

"Reference pose not found"

• Explanation: This error occurs when the reference pose data is unavailable or incorrectly specified.
• Solution: Ensure that the reference pose is correctly defined and accessible to the node for processing.
